Abstract (en)
There is provided a process for producing single-walled carbon nanotubes with an increased diameter, characterized in that it comprises a diameter-increasing treatment step of heating carbon nanotubes of a raw material at a degree of vacuum of 1.3 x 10 -2 Pa or below and at a temperature ranging from 1500 to 2000 °C, preferably 1700 to 2000 °C.
